A cup of sweet cherries (about 21 fruits) contains roughly 18 grams of sugar. That’s less than a banana and comparable to a cup of blueberries, putting cherries in the moderate range for fruit sugar content.
Sugar Content per Serving
The standard serving size for sweet cherries is one cup, which works out to about 21 cherries or 140 grams. In that cup, you’re getting approximately 18 grams of total sugar. To put that in perspective, a medium apple has about 19 grams, a banana around 14, and a cup of grapes close to 23. Cherries sit comfortably in the middle of the fruit sugar spectrum.
If you’re snacking casually and eating 10 cherries, you’re looking at roughly 8 to 9 grams of sugar. A large bowl of cherries (two cups) doubles the count to around 36 grams, which starts to rival a can of soda. Portion size matters more than most people realize with fruit, especially one as easy to eat mindlessly as cherries.
What Types of Sugar Are in Cherries
Not all fruit sugars are the same, and cherries have a distinctive profile. Per 100 grams of sweet cherry, the breakdown is approximately 5.4 grams of glucose, 4.6 grams of fructose, and 2.8 grams of sorbitol (a sugar alcohol your body absorbs more slowly). Unlike many fruits that are fructose-dominant, cherries lean slightly toward glucose, which your body processes differently. Glucose goes straight into your bloodstream for energy, while fructose is handled primarily by the liver.
The sorbitol content is worth noting. Sorbitol provides fewer calories per gram than regular sugar and absorbs more gradually, which contributes to cherries’ gentler effect on blood sugar. However, sorbitol can cause digestive discomfort in some people when consumed in large amounts, so if you notice bloating after a big bowl of cherries, that’s likely why.
Sweet vs. Tart Cherries
Sweet cherries (the Bing and Rainier varieties you find fresh at grocery stores) and tart cherries (Montmorency, typically sold dried, frozen, or as juice) differ significantly in sugar content. Sweet cherries contain roughly 12 to 13 grams of sugar per 100 grams. Tart cherries have about 8 grams per 100 grams in their raw form.
The catch is that tart cherries are rarely eaten raw. Dried tart cherries often have added sugar to offset their sourness, which can push the sugar content to 30 grams or more per quarter-cup serving. Tart cherry juice concentrate is similarly high. If you’re watching sugar intake and choosing tart cherry products, check the label carefully. The “healthier” option on paper can easily become the higher-sugar choice after processing.
How Cherries Affect Blood Sugar
Despite containing a moderate amount of sugar, cherries have a surprisingly low glycemic index of about 20, with a glycemic load around 5 per serving. For context, anything under 55 on the glycemic index is considered low, and a glycemic load under 10 is also low. This means cherries raise blood sugar slowly and modestly compared to foods with the same amount of carbohydrates.
Several things explain this gentle effect. A cup of sweet cherries provides about 2.5 grams of dietary fiber, which slows digestion and the rate at which sugar enters your bloodstream. The sorbitol content helps too, since it absorbs more gradually than glucose or fructose.
Cherries also contain anthocyanins, the pigments responsible for their deep red color. These compounds slow sugar absorption in the gut by interfering with the enzyme that converts complex sugars into glucose during digestion. They also appear to improve how cells respond to insulin, meaning your body needs less insulin to manage the sugar that does enter your bloodstream. This combination of fiber, sorbitol, and anthocyanins is why cherries behave better in your body than their sugar number alone would suggest.
Fresh, Dried, and Canned Compared
How cherries are prepared dramatically changes the sugar picture:
- Fresh sweet cherries: About 18 grams of sugar per cup. No added sugars, full fiber content intact.
- Dried sweet cherries: Roughly 30 to 40 grams of sugar per quarter cup. Water removal concentrates the natural sugars, and many brands add extra sugar or juice concentrate.
- Canned cherries in heavy syrup: Around 35 to 40 grams of sugar per half cup, with most of the extra coming from the syrup.
- Maraschino cherries: About 14 grams of sugar in just two cherries. These are essentially candy.
- Frozen sweet cherries (unsweetened): Nearly identical to fresh, around 17 to 18 grams per cup. This is your best option when fresh cherries are out of season.
The jump from fresh to dried is where most people get tripped up. A quarter cup of dried cherries looks like a small handful but packs twice the sugar of a full cup of fresh ones. If you’re adding dried cherries to oatmeal or trail mix, measure them rather than pouring freely.
How Cherries Compare to Other Fruits
Per cup of whole fruit, here’s where cherries land in the sugar ranking:
- Strawberries: ~7 grams
- Raspberries: ~5 grams
- Blueberries: ~15 grams
- Sweet cherries: ~18 grams
- Pineapple: ~16 grams
- Mango: ~23 grams
- Grapes: ~23 grams
Cherries have more sugar than most berries but less than tropical fruits and grapes. Their low glycemic index, however, means they cause less of a blood sugar spike than several fruits lower on this list. Sugar content alone doesn’t tell the whole story of how a fruit affects your body.
